Anyone with technical knowledge RE: ADS L1290

Hi,

I was fortunate to purchase an almost new pair of ADS L1290 speakers.

Unfortunately one of the tweeters is not functioning. I found the owners manual In the "offical" manual it states that the speakers have fuses for both the midrange and tweeter speakers.

In an addendum entitled "Dear ADS L1290 Owners", it states that "An advanced solid state tweeter protector, located inside the speaker, replaces the tweeter fuse". "This protector interrupts the signal to the tweeter only when overload occurs, then automatically restores proper operation after the signal level is reduced." Signed Dick Moore, Technical Assistant to the President"

Please post if you think if this issue can be repaired or if this tweeter should be replaced.

Tilt the speaker forward with the help of a friend
-undo and remove all the tweeter screws except the one on top
-slowly unscrew the top bolt
-in 90% of the cases, the tweeter will fall forward and stay in place, hanging by the bolt. Hold the tweeter with one hand while slowly unscrewing the last bolt.
Avoid any contact with the tweeter dome.
-Mark the positive and negative terminals with a laundry marker pen before removing the wires
GOOD LUCK
